New Delhi [India], Dec. 13 (ANI): Communist Party of India (CPI) leader D. Raja on Tuesday said that the Augusta Westland chopper scam case should be pursued in an unbiased and neutral manner. "This is an issue which has been raised many times and now investigation is on. It is for the law enforcing authorities to pursue the matter in a manner which should not give any apprehension of targeting some particular bureaucrats, appointed by the previous government," he told ANI. Raja further said that the case should be pursued keeping in view, the country's interest. "Neutral approach must be there in pursuing and investigating the case because, the way it is pursued, can lead to apprehension of political vendetta and such an impression should not be created. Law must take its course and there must be very neutral and unbiased investigation." he said. Former Air Chief Marshal (retired) chief, S.P.
